ENDOSCOPIC LIGATING INSTRUMENT

摘要

A flexible endoscopic instrument is provided with a plurality of elastic ligating rings (50) mounted to a tubular member (152) affixed to the insertion end of an endoscope (100). The rings (50) are adapted to be dislodged therefrom in sequence at selectively controlled times for treating multiple lesions during a single insertion of the endoscope (100) into a body organ. Each of the elastic rings (50) can be dislodged from the endoscope (100) and placed in ligating relation to a lesion when lesion tissue is drawn into the tubular member (152) by a suction force applied through the suction channel of the endoscope (100) and each of the rings (50) can be applied to a different one of the multiple lesions in the body organ during a single insertion of the endoscope (100).
